Historically, presidents are expected to avoid publicly criticizing the Fed to avoid the appearance of inappropriately influencing montary policy.

Trump has made clear he sees rising interest rates as a threat to the broader US economy. He has broken with longstanding traditions in presidential politics by openly criticizing the Fed.

When asked whether he regrets nominating Powell to chair the Federal Reserve, Trump said it’s “too early to say, but maybe.”

Trump’s comments on Tuesday come a week after he described the Fed as his “biggest threat,” the Associated Press reported. The president also had words for Powell in the AP report, and grumbled at the Fed’s plan to keep raising interest rates into 2019.
